Notion is locked. This isn’t.

A Notion-style workspace you own.

Block editor + nested pages + DB views — yours to fork into a KB, a CRM, a recipe vault. The code is yours. Forever.

This is a live mock. Same UX you ship after pasting PROMPT.md into Claude Code.

Why this, not Notion.

You’re not subscribing. You’re cloning.

Same UX. Different ownership model. Compare the four things that matter once you go past the demo.

Comparison axis	Notion	Need for Build scaffold
Pricing	$8–15 per user, per month. Forever.	Free forever. You pay only your own hosting (Supabase free tier covers the first 50K MAU).
Data ownership	Their servers, their region, their backup policy. Export is your only escape.	Your Supabase project, your S3 backups, your region. The data never leaves your infra.
Privacy	Their compliance posture, their employees with access, their AI training opt-outs.	RLS-scoped per workspace. Only your team — and the rows your policies allow.
Extensibility	The blocks they ship. The widgets they approve. Wait for the roadmap.	Full Next.js + Drizzle source. Fork any block, ship any view, glue any integration today.

What you ship

Ten files. One paste into Claude Code.

Every file the scaffold ships, with size and one-line description. Download once, build forever.

Stack

Boring tech that ships, not lock-in.

Each pick justifies its slot in the bundle — and every piece is swappable.

Next.js 16 + RSC

Server Components default, edge runtime native, useOptimistic + Server Actions standard 2026 pattern.

Supabase Postgres + RLS

Multi-tenant with workspace_id JWT claim. Page tree stored as ltree path for fast subtree queries.

TipTap + ProseMirror

Block-based editor with 50+ extensions: headings, lists, code, mentions, embeds, slash commands.

Drizzle ORM

Edge-compatible, no codegen, smaller bundle. Direct SQL for ltree page-tree queries.

tRPC

Type-safe internal API for workspace/page/block CRUD without REST plumbing.

Tailwind v4 + OKLCH

@theme directive, perceptually-uniform palette for the customizable workspace themes.

Fork patterns

Same engine. Five different products.

Start from the wiki, end up shipping something else. Each fork is a copy-paste away from the demo.

Internal company wiki

pages → handbook docs · tree → org structure · SCIM-synced groups · own the audit log

Customer knowledge base

pages → public articles · `published` toggle · slug routes outside workspace · ship your own Algolia

Project hub

pages → meeting notes + specs · link blocks → Linear/GitHub issues · weekly digest from your domain

Recipe / collection vault

pages → recipes · DB views → cuisine/diet/cost · cross-linked sub-pages · no per-seat tax

Customer voice / feedback

pages → call transcripts · tag by sentiment · weekly digest to Slack · keep the data forever

Architecture

The whole file tree.

Every directory, every route, every migration. What you’ll see right after `unzip`.
